A skate board ramp is built on an incline so that it rests on a porch that is 1.3m high. The bottom of the ramp is placed 2.5m f

mr_godi [17]

Answer:

θ = 27.47°

Step-by-step explanation:

This problem can be represented as a right-angled triangle, as shown in the diagram below.

To find θ, we apply the tangent part of the trigonometric ratios SOHCAHTOA:

tanθ = $\frac{opposite}{adjacent}$

In the diagram, opposite = 1.3 m and adjacent = 2.5 m

Hence:

tanθ = $\frac{1.3}{2.5}$

tanθ = 0.52

θ = $tan^{-1} 0.52$

θ = 27.47°

The ramp forms 27.47° with the ground.

How do you solve this 2 step equation: 8+b/-4=5

Delicious77 [7]

I'm going to rewrite the equation assuming this is the correct form:
$8 - \frac{b}{4} = 5
\newline
-8 + 8 - \frac{b}{4} = 5 - 8
\newline
(-4)\cdot -\frac{b}{4} = -3 \cdot (-4)
\newline
b = -12$

Indiana is hiking at a rate of 5 miles per hour. At this rate, how long will it take her to hike 22 miles?

Pie

$v =\dfrac{d}{t}$

$5 = \dfrac{22}{t}$

$t = \dfrac{5}{22}$

She will take $\dfrac{5}{22}$ hours or 13 minutes and 38 secs.
